LATH-FEEDER FOR PAPER-DRIERS.

SPECIFICATION forming part of Letters Patent No. 574,692, dated January 5, 1897. Application filed December 20, 1895. Serial No. 572,784. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM H. WVALDRON, of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a new and Improved Lath-Feeder for Paper-Garriers, of which the following is a full, clear, and exact description.

The invention relates to lath-feeders for paper-carriers,such asshown and described in the Letters Patent of the United States No. 514,794, granted to me on February 13, 1894.

The object of the present invention is to provide a new and improved lath-feeder arranged to insure a positive delivery of a single lath at a time from the feed-chute to the carrier-chains.

The invention consists principally of a carrier mounted to turn and adapted to carry one lath at a time from the chute to the carrierchain.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement as applied. Fig. 2 is a crosssection of the same on the line 2 20f Fig. 1, and Fig. 3 is a sectional side elevation of a modified form of carrier.

The improved lath-feeder for pa per-carriers is provided with a suitably-constructed frame A, supporting a lath-feeding hopper B, into which the laths C are promiscuously thrown, to be arranged in single file at the lower end of the hopper B by a cylinder D and a feedregnlatin g wheel E, both rotating in the same direction, the wheel E serving to hold the lath back, so as to permit a single lath to pass into the chute F, arranged on the inside of the sides of the frame A.

The lower'end of the chutes F discharge upon carriers G, each provided with a radial slot or notch G, adapted to receive in the lath leaving the chutes F and carry said lath to the carrier chains or belts H, provided with fingers or looks H for moving the lath upward to permit the paper or fabric to be looped upon the corresponding lath in the usual manner. The carrier chains or belts H pass over sprocket-wheels I, secured on a transverselyextending shaft I, j ournaled in suitable bearings attached to the main frame A and driven from suitable machinery forming part of the general machine.

Each carrier G is made in the form of a segment with its peripheral surface in engagement with the lower edge of the lowermost lath in the chutes F, so that the lath is held in place in the chutes until the carriers turn and bring the notches G in alinement with the lowermost lath, so that this lath passes into the notches G, and the turning of the carriers in a downward direction moves this lath from the chutes to the carrier-chain H to be engaged thereon by the hooks or fingers H, which push the lath out of the notches G and carry the same upward, as previously described.

Each carrier G has an oscillating motion, and for this purpose is mounted on a trans verselyextending short shaft G journaled in suitable bearings arranged on the frame A at the lower end of the chutes F, an d on the outer end of each shaft- G is secured a gearwheel G in mesh with a gear-wheel J, se-

cured on a transversely-extendin g shaft journaled in suitable bearings, said shaft carrying both gear-wheels J, as plainly shown in Fig. 2, so that an oscillating motion is simultane ously given to both carriers.

On one outer end of the shaft J are secured crank-arms K, in which is fitted a block L, through which passes a rod L, pivotally connected with a crank-disk N, held on the shaft for the cylinder D and rotating with the latter. On the rod L and on the opposite sides of the block L are coiled springs L L for imparting a swinging motion to the crank-arms K, so as to turn the shaft J forward and back-- ward to impart the turning motion in a like direction to the carriersG, so as to carry a lath from the lower end of the chute F to the carrier-chain H, as previously explained. By the use of the springs L L a yielding motion is given to the crank-arms .K, so as to insure a proper delivery of the lath.

Instead of employing oscillating carriers G, I may employ carriers G (see Fig. 3,) mounted to rotate and provided with diametricallyarranged slots G and G, so that upon every half-revolution one of the slots engages a lath and carries it to the carrier-chains H, as previously explained. The movement given to the carriers G4 is preferably intermittent, so as to insure a proper taking up of the lath and delivery of the same to the chains H.

Having thus fully described my invention, 1 claim as new and desire to secure by Letters Patent- 1. A device of the class described, provided with an oscillating carrier adapted to carry one lath at a time from the chute to the carrier-chain, substantially as shown and described.

2. In a lath-feeder, the combination of a delivery-chute having an outlet-opening accommodating only a single lath, of a lath-carrier mounted to turn and having a plain rounded surface normally closing the outlet of the chute and sustaining the laths in single succession in the chute, the carrier further having lath-receiving slots approximately equal in size to the chute-outlet, and movable to and from the latter as the carrier is moved on its axis, substantially as described.

3. In a device of the class described, the combination With a delivery-chute for the lath and an oscillating carrier-chain adapted to receive the lath, of a segmental carrier mounted to oscillate and formed With a radial slot or notch, said carrier holding said lath normally in place in the delivery-chute, substantially as shown and described.

4. In a device of the class described, the combination with a delivery-chute for the lath and a carrier-chain adapted to receive the lath, of carriers mounted to turn and arranged between said chute and carrier-chain, to feed the lath singly to the latter, and means for imparting a motion to said carrier, said means including a spring acting to relieve the carrier of sudden movement by its said actuating means, substantially as shown and described.
